9 Router Bits Every Small Woodworking Business Needs

If you're running a small woodworking business, your router bits need to do real work—not sit in a drawer.

The right core set lets you cut cleaner, work faster, and take on more jobs without constantly buying specialty tooling. Whether you're building furniture, cabinets, signs, or small-batch products, these 9 router bits cover the majority of what actually happens in a shop.

This is not about owning everything. It’s about owning the right tools that pay for themselves.

AMS-410 Must-Have Router Collection (with 1/2" Shanks) Includes (left to right): Slotting Cutter System, with 3 Wing Cutter & 3 Ball Bearing Guides (to adjust depth); 1/4" Diameter Straight Plunge High Production Bit; 3/8" Diameter Spiral Plunge Bit / Upcut; 1/2" Diameter Straight Plunge Bit; 1/2" Diameter Flush Trim Bit; 1/2" Deep Rabbeting Bit; 10 Degree Dovetail Bit; 45 Degree Chamfer Bit; 1/4" Radius Corner Round Bit; 3/8" Radius Cove Bit

TL;DR: What to Buy First

If you're building your first serious set, start here:

• Flush Trim Bit – for templates, duplication, and clean edges
• Straight Bit – for grooves, dados, and general cutting
• Roundover Bit – for easy, sellable edge finishing
• Rabbeting Bit – for joinery and back panels
• Spiral Downcut Bit – for clean top edges in plywood and laminates

Then expand based on your work:

• Add Chamfer for modern edges
• Add Cove for decorative profiles
• Add V-bit for signs and personalization
• Add Spiral Upcut for faster cutting and CNC work

Why These 9 Router Bits Matter

Small shops don’t win by having the most tools. They win by having the most useful tools.

Every bit on this list helps you:

• Produce repeatable parts
• Deliver clean, professional finishes
• Expand into higher-value products
• Reduce sanding, rework, and wasted material

If a bit doesn’t help you do at least one of those, it probably doesn’t belong in your core kit.

1. Flush Trim Bit (Template Work)

What it does

A flush trim bit uses a bearing to follow a template or reference edge and cut your workpiece to match it exactly.

Why it matters

This is how small shops scale. One good template turns into 10, 50, or 500 identical parts.

• Perfect for repeatable production
• Essential for curves and shapes
• Cleans up rough cuts fast

How to choose

Pick based on bearing position (top vs bottom), cut length, and material thickness. For heavier work, go with a 1/2" shank for better stability.

2. Straight Bit

What it does

The go-to utility bit. Cuts grooves, dados, mortises, and pockets.

Why it matters

If you're doing joinery, hardware installs, or basic routing, you’ll use this constantly.

• Grooves and dados
• Mortises
• General cutting tasks

How to choose

Match the diameter to your most common cuts. Smaller for detail, larger for strength. If your router allows it, 1/2" shank = smoother, more stable cuts.

3. Roundover Bit

What it does

Rounds over sharp edges into a smooth radius.

Why it matters

This is one of the fastest ways to make a product feel finished—and more valuable.

• Furniture edges
• Shelves and tops
• Boxes and small products

How to choose

The radius determines the look. Small = subtle. Large = bold and tactile. Choose based on your product style.

4. Chamfer Bit

What it does

Cuts a beveled edge instead of a rounded one.

Why it matters

Clean, modern, and easy to control. Many shops use this instead of a roundover for a sharper look.

• Modern furniture
• Boxes and casework
• Quick edge breaks

How to choose

Look at the angle and cutting height. A bearing-guided version keeps results consistent across batches.

5. Cove Bit

What it does

Creates a concave (inward-curving) profile.

Why it matters

Not every shop needs it daily—but it’s a simple way to add decorative value and stand out.

• Frames and plaques
• Decorative edges
• Traditional designs

How to choose

Smaller coves = subtle detail. Larger coves = more visual impact. Choose based on your product line.

6. Rabbeting Bit

What it does

Cuts a shoulder (rabbet) along the edge for joinery and panel fitting.

Why it matters

This is a workhorse for cabinets, boxes, and casework.

• Back panels
• Drawer bottoms
• Basic joinery

How to choose

Look for sets with interchangeable bearings so you can adjust rabbet size without buying multiple bits.

7. V-Bit (Signs & Personalization)

What it does

Cuts angled grooves for lettering, engraving, and decorative lines.

Why it matters

This bit can unlock entirely new revenue streams—signs, gifts, branding, personalization.

How to choose

The angle determines detail vs boldness. Narrow = fine detail. Wide = bold, readable cuts.

8. Spiral Upcut Bit

What it does

Pulls chips upward, improving chip evacuation and cutting efficiency.

Why it matters

Great for deeper cuts, faster feed rates, and CNC roughing.

• Grooves and slots
• Mortises
• CNC work

How to choose

Choose based on diameter and cut depth. Just remember: upcut bits can leave a rougher top edge.

9. Spiral Downcut Bit

What it does

Pushes fibers downward for a cleaner top surface.

Why it matters

If you work with plywood, laminates, or finished surfaces, this is critical for clean results.

• Clean top edges
• Cabinet parts
• CNC finish passes

How to choose

Best for shallow to moderate cuts where surface quality matters most. Pair with an upcut bit when needed.

If You Do X → You Need This Bit

• Templates / repeat parts → Flush Trim
• Grooves / joinery → Straight Bit
• Sellable edges → Roundover
• Modern look → Chamfer
• Decorative detail → Cove
• Cabinets / boxes → Rabbeting
• Signs / personalization → V-Bit
• Fast cutting / CNC → Upcut
• Clean top finish → Downcut

Common Mistakes (Wrong Bit = Bad Results)

• Using the wrong spiral direction
  Upcut = better chip removal, rougher top edge. Downcut = cleaner top, worse chip evacuation.
• Skipping flush trim for repeat work
  Templates + flush trim = consistency. Guesswork = inconsistency.
• Choosing edge profiles randomly
  Your edge style affects how your product feels—and sells.
• Buying specialty bits too early
  Master the core set first. That’s where most revenue comes from.
• Using small shanks for heavy cuts
  When possible, 1/2" shank = better control and less vibration.
